POTENTIOMETRIC BIOSENSOR FOR ASPARAGINE DETECTION

Dual amperometric–potentiometric biosensor detection system for monitoring organophosphorus neurotoxins

A dual-transducer flow-injection biosensor detection system for monitoring organophosphorus (OP) neurotoxins is described. Such simultaneous use of different physical transducers in connection to the same (organophosphorous hydrolase (OPH)) enzyme enhances the information content and provides discrimination between various subclasses of OP compounds. While the potentiometric biosensor responds ...

Development of a monoclonal antibody based potentiometric biosensor for terbuthylazine detection

In the present paper a new potentiometric biosensor for terbuthylazine (TBA, a herbicide widely utilized in agriculture) suitable for this determination in water samples is shown. As previously described, monoclonal antibody (mAb) showing high specificity for the analyte was utilized as biological element to perform the biosensor assay. A light addressable potentiometric sensor (LAPS), measurin...

A Potentiometric Flow Biosensor Based on Ammonia-Oxidizing Bacteria for the Detection of Toxicity in Water

A flow biosensor for the detection of toxicity in water using the ammonia-oxidizing bacterium (AOB) Nitrosomonas europaea as a bioreceptor and a polymeric membrane ammonium-selective electrode as a transducer is described. The system is based on the inhibition effects of toxicants on the activity of AOB, which can be evaluated by measuring the ammonium consumption rates with the ammonium-select...

Development of Potentiometric Urea Biosensor For Clinical Purposes

This review summarizes the studies carried on the development of potentiometric urea biosensor in laboratory using urease from Cajanus cajan (local Arhar). The enzyme used was free without any immobilisation over matrix. The electrode used egg membrane or cellophane paper making ionic diffusion possible across the two solutions. Underlying the importance of this study is the fact that urea is t...
